To all whom it may concem:

Be it known that LJornv 'E. oom, a citizen of the United States, res: atFindlay, in the county of Hancock and tate of Ohio; have invented a newand useful Outlet-Valve for Oil-Tanks, of which the follow is-a specifi'cation. 4

The prwent invention relates to improvements in outlet valves for oiltanks, or for tank cars of other types, wherein it is desirable todispose the valve the tank to drain the contents thereof, one ob ect ofthe invention. being the provision of a simple on of valve, the casingof which is adapted to be threaded from above mto the upper end of theoutlet pipe of the tank and carry a frusto-coniwl valve memberresiliently held seated in place, the upper aid of the casing being openfor ready access to the valve While the sides of the casing are providedwith diametrically ports for registration with the diametricallydisposed ports of the hollow valve, which is opened through the lowerend for directing the fluid into the outlet P?- p A. fin-thaobject ofthe present invention, is the provision of a valve of this character,which is simple, inexpensive and durable in construction and which istherefore thoro y practical and useful.

1th the foregoing and other objects in view which will appear as thedescription proceeds, the invention residm in the combination andarrangement of parts and in the details of construction hereinafterdem'bcd and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without deErting from the spirit of theinvention.

the drawings-Figure 1 is a vertical central sectional view through thelower portion of an oil tank and the upper portion of an outlet pipethereof, with the present valve in operable relation thereto, the saidvalve shown in section. Fig. 2 is a side elevation of the complete valveand valve casinggperse. Fig. 3 is a top plan view thereof.

to the drawings, the numeral 1 designates the tank which is providedwith the outlet pipe 2, the upper end of which is provided with theinteriorly screw threaded portion 3 for the reception of the exteriorthreads 4 of the lower tapered end of the valve casing 5. The valvecasing 5 is dis posed to'fit within the tank in a vertical position andis provided with diametrically disposed ports 6, the lower edge of eachof which is adjacent to the lower edge or bottom line of the tank.Mounted within the casing is the hollow frusto-coniml valve 7, which isprovided with the two ports 8 diametrically disposedth thin the walls:Ethlpreof for registrationwi eportsGoteca' 5, so that the liquid withinthe tank mai' directed through said ports and downwardly through theopen end of the valve 7 and the easing into the outlet pipe The upperend of the valve 7 is closed, and is provided with the concentricallydisposed stem 9 which is provided with the centrally disposed angular orsquare socket 10, the purpose of which will presently appear.Surrounding the stem 9 and exerting a presm-e downwardly to hold thevalve 7 seated properly the tapered portion of the casing 5. is a spring11, the upper end of which is held in proper position by means of thebridging plate 12, whose terminals are clamped to the lugs 14 of thecasing 5 as illustrated.

The bridging member 12 is provided with a circular opening 13, for thereception of the operating stem 15, which is provided with a squared endfor the gement with the opening or socket 10 of the stem 9 at one end,and with the handle 16 at the oppos'te end, said stem 1-5 being extendedupwardly through the tank intenorly thereof, a) that the handle 16 maybe operated to open and close the valve 7.

From the foregoing description, it is evident that with the presentconstruction of the valve, the member 5 is merely to be oscillated orrotated one-quarter revolution to place the ports thereof in regiqrationwith the ports of the casing. and that the liquid is directed throughthe ports in teriorly of the galve ant} valve easing into the upper end0 the out et pipe. t e u r end of the valve being sealed, so that e willhold the same downwardly and thus prevent the leakage of the fluid orliquid through the upper open end of the valve easing into the outletpipe 2.

By this construction of valvethe member 5 is rotated in the same planeand the amount of fluid is regulated entirely by the codperation of theports of the casing and vale requiring merely a quarter turn to placethe ports in full registmtion or out of registration.

It is also apparent that by reason of the bridging};} member 12 and itsproper connection wi the casing, that the spring 11 will be held inplace to exert the proper pres sure to maintain the haste-conical valvemember 7 properly seated in a tight condition and vet so that the samemay be pr0perly oscillated.

By threading the upper inlet end of the outlet pipe 2, the present valvemay be properly asembled before introduction therein as it is merelynecessary to utilize the lugs H to rotate the casing to cause thethreaded portions 3 and 4 to properly engage.

What is claimed is:

1. The combination with a liquid tank, and an ouflet pipe thereforhaving an interiorly threaded portion of slightly greater diameter thanthe inlet of the pipe, of a valve for controlling the pipe. including acasing having a frusto eonical lower end, said end being exterior-l3threaded for engagement with the threads of the outlet pipe, afrnsto-conical valve having a socket formed therein from the lowerreduced end thereof and provided with diametriwlly disposed ports. saidcasing in the conical rtion thereof being provided with diametricallydisposed ports for regifiration with the ports of the valve, a stemcarried by the frusto-conical valve and extending in an oppositedirection to the socket thereof,

a spring surrounding said stem, a bridging member conneded across thevalve casing andexerfingapressnreupon thespringto hold the valve seatedwithm the msmg, and means for operating the valve extending through thebridging member and engaging the fiem.

The combination with a liquid tank, and an outlet pipe therefor havingan interiorly threaded portion of slightly greater diameter than theinlet of the pi of a valve for controlling the pipe, uding a casinghaving a frusto-eonical lower end, said end being exterior-1y threadedfor engagement with the threads of the outlet pipe, 2 frusto-coniealvalve ha a socket formed therein from the lower need end thereof andprovided with diametrically disposed ports, said casing in thefrusto-oonical portion thereof being rovided with diametrically disposedaErr-ts or registration withtheportsofthev e,astemearriedby thefrusto-conical valve and extending in an opposite direction to thesocket thereof, a spring surrounding said stem, a bridging member1oonnectedacross the tialve casing an exerting a pressure 11 n e to holdthe valve seated the eau l the said stem being provided with an angularsocket in the upper end thereof and said bridging member being providedwith a circular opening concentric to the socket, and an operating stemhaving an end seatable within the angular socket of the valve stem andextending through the drenlar opening of the bridge, whereby the valvemay be oscillated In testimony that I claim the foregoing asmyowmlhaveheretoafixedmyslgna ture in the presence of two J OHN E.
